The dual coding theory proposed by Paivio attempts to give equal weight to verbal and non-verbal processing. Paivio (1986) states: Human cognition is unique in that it has become specialized for dealing simultaneously with language and with nonverbal objects and events.
Therefore, high temperatures are required to break these strong bonds to turn it into a liquid state â¦ . Thus the melting point of graphite is high, same goes for diamonds. Even though it is a covalently bonded compound, these 2 examples are the only ones that have high melting points. The melting point of graphite is 3500 c and 6332 f, specific gravity is 2.25, pounds per cubic inch is .812, 21 people found this useful.
A percent yield over 100% could be due to water not completely dissolving from the product. 4. Our crude aspirin had a melting point range of 56.0-78.2 C. Our recrystalized aspirin product had a melting point range of 110.0-116.2.We observed a melting point range of 127.0-135.0 with commercial aspirin while the actual melting point is reported as 134-136 C from sigma-Aldrich online. percent yield over 100% could be due to water not completely dissolving from the product. 4. Our crude aspirin had a melting point range of 56.0-78.2 C. Our recrystalized aspirin product had a melting point range of 110.0-116.2.
